Once upon a time, a little boy (who we will call M) wore holes in his socks. M waited and waited for his mother to fix them. She was quite slow, it seems that she enjoyed knitting the socks more than fixing
So one day M told her how much he missed wearing the socks. M's mother knew the time had come and sat down to do the simple fix job. (she giggled a little when she realized that all the holes were on the left heel.)
And before M could finish playing, his mother brought him the finished socks. But being the silly Mommy that she is, she only took pictures of the sock to which she had lost the matching yarn. M didn't care, he was already off wearing all the socks at once.
